Question

in triangle ABC angle A=70° and angle B=60° then the measure an exterioe angle of triangle can be ​

Answer 1

Answer:

50

Step-by-step explanation:

a triangle has180 deg . so 70 + 60 +c = 180

130+c=180

c=180 - 130

c=50

Answer 2

In ∆ABC,

angle A+angle B+angle C=180

70+60+angle C=180

angle C=50

angle ACF=180-50

=130

angle CAD=180-70

=110

angle ABE=180-60

=120
